Demon-slayer Lin Feng went down the mountain due to his master's mission of "monitoring abnormal auras in the city", and accidentally got involved in the Internet celebrity circle. He discovered that the traffic of Internet celebrities affiliated with MCN "Xingyao Media" was abnormal - behind it was the practice of "traffic demon" to absorb users' attention, while the company CEO Zhao Tianlei secretly practiced the "traffic soul-eating technique" to convert the trust of ordinary people into demon power. Lin Feng sneaked into the company as an "intern operation", pretending to adapt to urban life while collecting evidence, but unexpectedly crossed paths with Su Xiao, a new Internet celebrity who was parasitized by a traffic demon.
